Ask Lemmy
A Fediverse community for open-ended, thought provoking questions
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, toxicity and dog-whistling are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
6) No US Politics.
Please don't post about current US Politics. If you need to do this, try !politicaldiscussion@lemmy.world or !uspolitics@lemmy.world
7) No Hit-and-Run questions.
Please don't delete your post for no apparent reason. If you plan on deleting a question later, say so in the post, or if you feel that you have a good reason to remove it, message a mod beforehand. It's not fair to the ones who took their time to answer, and it's not in the spirit of the community.
8) No Bots.
Posts or comments from bots, LLM's, AIs, Neural Networks, Transformers, or Marvin the Paranoid Android are not welcome in AskLemmy. Real humans only please.
Reminder: The terms of service apply here too.

Do I get a million for every metric tonne of water transferred?
It's 12006km from Sydney to Los Angeles as the bird flies. Garden hose is ~$2/m. I'd break even after 25 metric tonnes.
A garden hose is about 2cm in diameter, you're gonna need a pretty massive pump to get any flow rate to speak of through that hose. I'll be back with numbers for you ;)
The hose itself would require 3.77 million litres to fill. But after that! Profit!
At standard domestic pressure (3.5bar), we'd expect 60 litres per minute through that hose. Just filling the hose would take 52 days.
I filled an 800 litre hot tub up in abiut 2.5 hours.
1000 litres won't take long.
Although you also have to account for distance....
Fill it by a 12000km long 2cm wide tube. Do not underestimate the pressure needed to get a reasonable flow. Ever tried soak up honey with a straw?
